The present invention provides a process for obtaining solid recovered fuel and synthesis gas from a waste-based feedstock, comprising the steps of: I. converting the feedstock into a solid recovered fuel by means of a number of parameters pertaining to waste sorting, selection, comminution and/or screening; II. gasifying under suitable reaction conditions at least a portion of the solid recovered fuel to produce synthesis gas and by-product(s); and III. optionally cleaning at least a portion of the synthesis gas to produce clean synthesis gas and wastewater, wherein one or more of the solid recovered fuel, synthesis gas, and by-product(s) of the gasification are analysed during operation of the process, and wherein data from said analysis is used to control one or more parameters of step I) in order to influence reaction conditions in step II, and optionally step III).

This invention relates to a power recovery process in waste steam/CO.sub.2 reformers in which a waste stream can be made to release energy without having to burn the waste or the syngas. This invention in some embodiments does not make use of fuel cells as a component but makes use of exothermic chemical reactors using syngas to produce heat, such as Fischer-Tropsch synthesis. It also relates to control or elimination of the emissions of greenhouse gases in the power recovery process of this invention with the goal of producing energy in the future carbonless world economy.

Methods and apparatuses for producing fuel and power from the reformation of organic waste include the use of steam to produce syngas in a Fischer-Tropsch reaction, followed by conversion of that syngas product to hydrogen. Some embodiments include the use of a heated auger both to heat the organic waste and further cool the syngas.

A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.

A processing facility is provided. The processing facility includes an asphaltenes and metals (AM) removal system configured to process a feed stream to produce a power generation stream, a hydroprocessing feed stream, and an asphaltenes stream. A power generation system is fed by the power generation feed stream. A hydroprocessing system is configured to process the hydroprocessing feed stream to form a gas stream and a liquid stream. A hydrogen production system is configured to produce hydrogen, carbon monoxide and carbon dioxide from the gas feed stream. A carbon dioxide conversion system is configured to produce synthetic hydrocarbons from the carbon dioxide, and a cracking system is configured to process the liquid feed stream.

The invention discloses novel diesel fuel compositions including a renewable diesel component, a fossil diesel component and an oxygenate component, as well as methods for manufacture and use of a combination of a renewable diesel component, and an oxygenate component for reducing particulate matter emissions.

A process for the manufacture of a useful product from synthesis gas having a desired hydrogen to carbon monoxide molar ratio comprises gasifying a first carbonaceous feedstock comprising waste materials and/or biomass in a gasification zone to produce a first synthesis gas; optionally partially oxidising the first synthesis gas in a partial oxidation zone to generate oxidised synthesis gas; reforming a second carbonaceous feedstock to produce a second synthesis gas, the second synthesis gas having a different hydrogen to carbon ratio from that of the first raw synthesis gas; combining at least a portion of the first synthesis gas and at least a portion of the second synthesis gas in an amount to achieve the desired hydrogen to carbon molar ratio and to generate a combined synthesis gas and subjecting at least part of the combined synthesis gas to a conversion process effective to produce the useful product.

Systems and methods are provided for integration of electrolysis with biomass gasification to generate synthesis gas that can be used for production of renewable fuels and/or other hydrocarbonaceous compounds. The hydrocarbonaceous compounds can include compounds formed by chemical synthesis, such as alkanes formed by a Fischer-Tropsch process or methanol formed by a methanol synthesis process; or the hydrocarbonaceous compounds can include compounds formed by fermentation, such as alcohols formed by micro-organisms that use the synthesis gas as an input feed.

A two-stage syngas production method to produce a final product gas from a carbonaceous material includes producing a first product gas in a first reactor, separating char from the first product gas to produce separated char and char-depleted product gas, and separately reacting the separated char and the char-depleted product gas with an oxygen-containing gas in a second reactor to produce a final product gas. The separated char is introduced into the second reactor above the char-depleted product gas. The solids separation device may include serially connected cyclones, and the separated char may be entrained in a motive fluid in an eductor to produce a char and motive fluid mixture prior to being transferred to the second reactor. A biorefinery method produces a purified product from the final product gas.
